Method and device for improving micro-suspension polymerization conversion rate

The invention discloses a method and a device for improving the conversion rate of micro-suspension polymerization. The method comprises the following steps: adding an emulsifier of a chain regulator and an initiator of a pH value regulator to form auxiliaries; dispersing and stirring the auxiliary agent, a vinyl chloride monomer and pure water according to a raw material mass ratio, and adding into a polymerization reaction kettle for polymerization; and carrying out early-stage constant-temperature polymerization and later-stage variable-temperature polymerization or early-stage constant-temperature polymerization in the kettle, and carrying out multi-stage serial groove type steam stripping on the latex after the reaction is finished, so as to finally obtain a special resin product with qualified finished product indexes. The polymerization kettle is connected with the discharge chute, the discharge chute is connected with the safe water-sealed tank, the discharge chute is connected ...
